What biomarkers should I test for Oily Hair?

The primary biomarkers to test for Oily Hair include: Fasting Insulin, DHEA-S. Measure Hormonal Drivers. Tracking Fasting Insulin, DHEA-S, and Zinc levels can reveal the root cause of your oily scalp.

How can biomarker testing help with Oily Hair?

Topical shampoos only treat the surface. Most people with oily hair have underlying hormonal imbalances that drive excess sebum production. Measure Hormonal Drivers. Tracking Fasting Insulin, DHEA-S, and Zinc levels can reveal the root cause of your oily scalp.

What is Fasting Insulin and how does it relate to Oily Hair?

High insulin levels stimulate the production of androgens, which increase sebaceous gland activity and oil production. Target range: 2.0 - 5.0 uIU/mL. If Insulin is above 5.0, focus on blood sugar stability: reduce refined carbs, increase protein intake, and practice time-restricted eating.

What is DHEA-S and how does it relate to Oily Hair?

DHEA-S is an adrenal hormone that can convert to testosterone. Elevated levels may indicate stress-driven oil production. Target range: Age-Optimized. If DHEA-S is high, manage internal stress through adaptogenic herbs, sleep optimization, and cortisol management.

Getting Started

Get the metabolic data

Standard physicals rarely test Insulin or DHEA-S unless there is an overt disease. Order a comprehensive panel that includes Fasting Insulin, DHEA-S, Testosterone, and Zinc.

Verify the trend

Hormonal shifts take time to settle. You need bi-annual data to see if your interventions are working. One test is a data point; two tests show a trend.

Address the root cause

Once you identify elevated markers, implement targeted interventions: insulin management through diet, stress reduction for DHEA-S, or zinc supplementation if deficient.

Track your progress

Retest every 6 months and observe both lab improvements and real-world changes in scalp oil production.

Why I built this guide.

"Hi, I'm Perry. I used to wash my hair twice a day. After testing my Fasting Insulin and discovering it was elevated, I made dietary changes. Within 6 weeks, my scalp oil production normalized. No more constant washing."
